The scalding tank A is substantially parallel sides bottom II and endwall I2 composed generally of of sheet metal I0, a at the delivery end,forward or receiving end, the latter having a curved upper portion I4,and the whole secured together in any suitable manner as by welding soas to be water-tight.

Above the sloping wall I3, and spaced therefrom, is a partition memberI5 so as to provide a passage I6 which may be made either rectangular orcircular in cross section, as desired. This passage I B has near the topa return bend I1 and near the bottom is provided with a screw propellerI8 which is carried on a shaft I9 suitably journaled in a 'water-tightstuii'ing box 20 and driven by any suitable source of power, such as a.motor 2I. 'Ihe shaft I9 may be equipped with a Suitable thrust collar orbearing (not n shown).

As the screw propeller I 8 is rapidly rotated, Water will be drawn in atthe power right-hand end of the passage I6, and will flow up through`the bend I1 and out past the plate I5a slightly y downwardly, afterwhich it will pass to the right through the tank and will eventuallyreturn through a grating 22, which is used to prevent any fowl whichmight become loosened from its shackle being drawn into the propeller.Along vcaught by it passage; is-placedffa series oiifstaggeredbail'lsv23; 24;? 2511andi25- whichrare solklooat'edlasl'to cause the water'aszittravels: between these bafllesrtobefclrunnedfintora series offeddy ucurrentsl f or! bringing aboutA a .th'oroughfv 5. wet-ting-J otfthe:f`iwl-"s-; These `battles-are` prefer removal-y andi for thief-purtheIsides! of the upper'.

A quick opening valve 30 of any well known type 25 which preferablyextends the width of the tank is provided at the lower right-hand end.This is opened for the purpose of cleaning the tank of this heavymaterial, and at the same time the apron 21 may also be removed. 'I'hespace 21a between the lastbalile 26 and the apron 21 serves as adowntake for the propeller and this, together with the direction takenby the waterentering this space, due to the baille 26, causes apronounced swirl to occur at 35 this point. A fowl in passing throughwill be and turned so as to cause many of its feathers to stand out awayfrom the body of the fowl, thereby permitting hot water to get to theskin beneath. The space 21a may be va- 40 ried by moving the apron 21,thereby increasing or decreasing the length of time the fowl isimmersed.

The tank is filled with water as by means of a pipe 3| connected to asuitable source of water 45 supply which is controlled by means of avalve 32. This water is preferably inserted behind the baliie 26. Whilethe Valve 32 is used for rapidly filling the tank, this pipe is alsoprovided with a small pet-cock or the like 33 which can be 50 opened asmall amount so as to provide a gradual vfeed of water which will makegood the losses,

due to the water splashed or carried out by fowls being scalded, andwill also provide a small overow over the Weir I2, The water in the tank55 fro , 3.
